SA is usually used in fiction just for pure empty shock value, it isn't about how it affects women, 90% of the time it is just used to "inspire" the men in the story to seek revenge. So usually I'd agree with this statement of it not belonging in a work of fiction.
However, context does matter, and it does just seem like this guy is mad that his cool TV fascists are doing actual fascist things instead of just being "badass" or whatever.
